You can put this solution on YOUR website! lets see here...
20 out of 50 like pizza.. how many would like pizza out of 450...
Ok lets solve this ...
20/50
is what you start off with as of right now.. Now lets divide from 450 to see how much times 50 goes into it!
450 Divided by 50=n
Since we don't know, we can make the multiplier n.
So far it is:
(20xN)/ 450
Now lets see..
___9
50)450
so that means the multiplier is 9..
~~~~~~~~~
(20x9) / 450
Now lets figure it out!!
20x9=180... so that means..
out of 450, 180 students would like pizza most likely.
